CompTIA Network+ (N10-007) — Question 54

A network technician has discovered a rogue access point placed under an empty cubicle desk. Which of the following should the technician perform to ensure another cannot be placed on the network?

Answer options

• A. Disable unused ports on switches
• B. Enable DHCP guard to detect rogue servers
• C. Configure WPA2 on all access points
• D. Use TACACS+ authentication

Correct answer: A

Explanation

Disabling unused ports on switches is essential to prevent unauthorized devices from connecting to the network, as it limits physical access. While enabling DHCP guard helps prevent rogue DHCP servers, it does not directly address unauthorized access points. Configuring WPA2 on access points enhances security, but it doesn't stop the placement of rogue devices. TACACS+ authentication is related to access control but does not mitigate the risk of rogue access points.
